IMPROVEMENT IN ADVERTISING-CALENDARS.

Specification forming part of Letters Patent No. 126,481, dated May 7,1872.

' of New York.

This invention relates to calendars which have a sheet, leaf, or tabletfor each month, said sheets, leaves, or tablets being hinged or fastenedtogether and to the back, so that any one month may be exhibited to viewby dropping that or another leaf, sheet, or tablet down. One side orother part of said sheets, leaves, or tablets is generally used foradvertising. The invention consists in the hinge or connectin g devicefor fastening the leaves, sheets, or tablets together and to the back,as hereinafter more fully described.

In the accompanying drawing, Figure 1 represents a back-side view of acalendar with the leaves, sheets, or tablets connected with the backaccording to my invention. Fig. 2 is a vertical section of Fig. 1 takenon the line a: m. Fig. 3 is a perspective view of my improved hinge orconnecting device detached.

Similar letters of reference indicate corresponding parts.

A represents the sheets, leaves, or tablets, twelve in number,representing the months of the year, which are connected together and tothe back B, according to my invention. 0 is my improved connectingdevice, which is made of a single piece of wire of proper size and ofany suitable metal. D D are eyes of the form shown. The ends of the wireare bent and the eyes D so formed that the eyes stand at right angleswith the straight portion E of the wire. The back and the leaves ortablets are perforated, as seen in the drawing at F. The straightportion E is placed in contact with the rear side of the back, where itis secured by a piece of cloth or leather, Gr, glued over it, as seen inFig. 1. This piece G keeps the wire in place or in contact with theback, but it is not indispensable to my invention. The ends H H of thewires are bent into the form seen after the sheets or tablets have beenslipped onto them. They are first passed through the perforations in theback from the back side when the tablets are put on, and the ends H Hare bent up, as represented in the drawing.

By making the eyes D D with flat sides H the calendar will rest flatlyagainst the wall when it is hung up, and the sheets can be attached andremoved much easier than if plain rings were used.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- In combination with the tablet A B, the de vice 0,formed of a single wire, having the straight portion E and the loops D,with straight sides H, as shown and described, for the purposespecified.
